# Scout create-series — author a new Atlas series ## Overview A *series* groups related Atlas research under `/series/<slug>/`. Scout's automated `series-suggestion` flow only adds new entries to series that **already exist** — inventing a new series is a human decision. This skill is that human-driven half: it walks you from a topic idea to a complete, reviewable series in the Atlas working tree. Deterministic file edits are done by `scripts/create-series.sh` (scaffold) and `scripts/add-to-series.sh` (members). The judgment — title, blurb, *which research belongs*, group labels, cover art — is yours, with this skill's guidance. **Boundaries (hard):** you only edit the Atlas **working tree** (`_data/series.yml`, `series/<slug>.md`, `series/<slug>.svg`). You do **not** commit or push — the human reviews and commits. Never edit existing series membership here (that's `add-to-series.sh` / series-suggestion). ## When to use - A cluster of published research shares a theme worth a landing page (e.g. a city/topic series). - You want to hand-curate a new grouping that the auto-suggester would never create on its own. ## Inputs - **ATLAS_DIR** — the Atlas checkout. Use `$ATLAS_DIR` if set, else a sibling `../atlas`, else ask. `local-setup.sh` can provide one. The manifest is `$ATLAS_DIR/_data/series.yml`. ## Flow ### 1. Definition - Get a **title** from the human (or propose one). Derive the **slug** with the repo's slugifier: `source scripts/slug.sh && slugify "<title
